Application filed February 8, 1922.

To all whom t may concern.

Be it known that l, lllriinrmr J. llnrsnin, a citizen oi the United States, and a resident ot Chicago, in the county ot Cook and `State ot illinois, have invented certain new and useful improvements in cetylene-Gasl Burners, ot which the following is a specification.

My invention relates to gas burners, more especially to burners tor burning acetylei'ie gas for cooking or' heating purposes. siderable diiliculty has been c'perienced heretofore in getting acetylene to burn in a simple burner structure with a uniform,

The structures which have heretofore been used ttor burning acetylene gas 'for heating` purposes' have been more or less complicated in endeavoring to obtain such uniform blue flame. i

rl`he object of my invention is to `prf'fluce a simple, inexpensive burn r, devoid all complicated structure, which ivill burn acetylene gas with a uniform, steady.` and clean blue llame and produce the volume ot heat required i'or cooking or heating purposes. l accomplish this by feeding the gas tangentially into a circular gas chamber together vvith air in sulilcient quantity, in which circular chamber' the gas and air may circulate to become thoroughly intermingled and from which chamber the mixture may flou' to burner openings to' be burned with a blue clean flame.

My improved construction and arrangement is incorporated in the burner structure shown on the accompanying drawing in Which- Fig. 1 is a side elevational vievv part-ly in section, and

Fig. 2 is a sectional vievv on plane 2-2 Fig. 1.

The body o'lf tl e burner shown is annular and of circular cross sections and has the circular or annular gas chamber 11 to which extends tangentially the gas inlet passagevvay 12. The end of the inlet passagevvay is surrounded by the threaded flange 13 extending from `the burner body and receiving the tube 14 which at its outer end receives the plug or fitting 15 having the passageway 16 and having the neck 1T for receiving a gas hose 18. ln the inner end oi the passageway 1G seated the gas tip 19 having the orifice 20, and adjacent Conf Serial No. 535,025.

the tip the tube 14 has the air inlets 21 whose area is made adjustable by means of the sleeve 22 having the openings 23, the amount of air `flowing in depending upon the degree of overlap of the openings 21 and 23. rllhe acetylene gas is projected under pressure through the tube 14- and tangentially through inlet 12 into the gas chamber 1.1, air being` entrained through the air holes 21 by the gas. rlibe air and gas mirto a degree in the tube 14e, but the more intimate mixture takes place in the chamber 11 in which the gas and air may circulate to become intimateliy mixed to produce an e'll'icient burning mixture which is distributed upwardly through the burner holes 2lin the top Wall oil the burner body `Where it will burn with a clean, blue, unitorni and steady 'flan/1e. The tangential inlet 12 accurately directs the incoming gas and air to its circular path through the chamber 11, there being no abrupt or violent deflection or stopping oi the gas and air, the unfinished inner Walls ot the chamber ail'ording just su'licient resistance to the flow to cause the gas and air to become thoroughly mixed before leaving the outlet rfhsre is not a chance for stagnation as in prior structures and the gas will burn clean and tree iroin sputtering or eX- plosion. The proper proportion ot gas and air can be readily adjusted 'or by turning the sleeve 22.

The housing 25 for the burner body is preferably of sheet metal and, as shoivn, is cylindrical. its bottoni being open and the holes 26 being provided in its side lor the circulation oit air around the burner body, the tube 22 entering at one side ott the housing as clearly shown. The sheet metal trame carries on its top the grid frame 27 for supporting cooking utensils. The burner body 10 is rigidly supported concentrically in the traine 25 by screws 28 passing through the Walls oi' the frame and into threaded lugs 29 extending radially 'from the body 10.

The burner structure described is very simple, light and efficient. The burner body is a simple casting devoid of intricate parts, the circulatory chamber 11 on account of its tangential inlet, accomplishing the final mixture of the and air and Jche proper directioning oi the mixture through the outlet openings Where it can then burn with a steady, uniorin, and clean blue llame to produce a large volume or heat.

Having described nly invention, I claim as follows:

In a gas burner, the Combination oil? a body having an annular gas chamber therein, an extension on said body providing' a gas inlet passageway to said Chamber, the outer and inner sides of said passageway being tangential respectively with the outer ard 10 inner sides ot' said Chamber where-hy will low directly tangentially from said passageway into said ohamber andV gas Combustion outlets from saiclehalnber.

In witness whereof, I hereunto subscribe niy name this 3d clay of February A. D.,
